Isobaric heat capacities and internal pressures of cyclopentanol at pressures up to 100 MPa and temperatures ranging from 293 to 318 K were determined by the acoustic method. The obtained results were compared
with those of pentan-1-ol in order to study the influence of the molecular configurations comprising cyclic and normal-chain structures on pressure and temperature dependence of the thermodynamic properties. It was found that the temperature and pressure coe±cients of internal pressure were sensitive to the structural organization of the liquid and re°ected the character of the interactions.
